Multimedia audio dock

Abstract

A multimedia audio dock is provided to support a portable electronic device so that the portable electronic device can stand on a plane. The multimedia audio dock includes two retractable arms formed by a plurality of sleeved-through tubes so that the length of the two retractable arms can be varied to a predetermined length. A biaxial hinge providing two rotational axes is connected to the two retractable arms, so that the two retractable arms may rotate relative to each other about two rotational axes. Two speakers provided respectively at the ends of the two retractable arms opposite to the ends connected to the biaxial hinge. The speakers receive the audio signals and output sound. And the electronic device is held between the two speakers moved by the two retractable arms, so that the portable electronic device can stand on the plane.

Description

PRIORITY STATEMENT [0001] This Non-provisional application claims priority under 35 U.S.C. § 119(a) on Patent Application No(s). 94211909 filed in Taiwan on Jul. 13, 2005, the entire contents of which are hereby incorporated by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of Invention [0003] The invention relates to an audio device, and in particular relates to a multimedia audio dock connected to a portable electronic device. [0004] 2. Related Art [0005] Presently, portable electronic devices such as personal digital assistants (PDA) or MP3 (MPEG Layer-3) players use earphones to provide audio output. Some models may be provided with miniature built-in speakers, but a single speaker can not provide stereo sound output, and the size is too small to output sufficient power, so that the volume of sound the speaker produces is too low to be heard clearly. Hence built-in speakers are useless in producing effective audio output. Generally, most of the user use earphones to prov...

AI Technical Summary

Benefits of technology

The invention is a multimedia audio dock that can hold and support a portable electronic device, allowing it to stand on a flat surface and play audio through the dock. The dock has two retractable arms that can change their length and rotate around each other, making it easy to secure and support different types and sizes of devices. The speakers on the arms can be moved to different positions, allowing the device to be placed in a vertical or lateral arrangement based on software settings. This makes it easier to play multimedia files and run application programs on the portable device. The main feature of the invention is the combination of the retractable arm and the biaxial hinge, which allows for varying the distance between the speakers and makes the dock applicable to different types and sizes of devices.

Problems solved by technology

The conventional speaker or dock for the portable electronic device is large sized and not convenient to be carried or to be kept somewhere, so that the audio output performance of the portable device is limited.
